The study investigated the martensitic transformation and its kinetics in the Ti-Ni-Cu-Hf shape memory alloy, revealing a strong dependence of transformation kinetics on cooling rate. The apparent activation energy was calculated and the variation of transition activation energy for a specific martensite fraction was studied to further characterize the martensitic transformation kinetics.
The purpose of the paper was to investigate the martensitic transformation and its kinetic of the Ti-Ni-Cu-Hf shape memory alloy. The Ti47Ni44Cu6Hf3 alloy would undergo a reversible B2 <-> B19' martensitic transformation during thermal cycling process. The apparent activation energy was calculated based on seven different DSC cooling curves. A strong cooling rate dependence of martensitic transformation kinetics was observed and the corresponding mechanism was discussed. Moreover, the variation of transition activation energy for a specific martensite fraction was studied to further characterize the martensitic transformation kinetics. (C) 2021 Elsevier B.V.
